I’m not sure about the catholic perspective but,
*“We have peace with God through our Lord Jesus Christ.” —Romans 5:1 (NIV)
**“For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life.” —John 3:16 (NIV)
*
I think you just got to have faith and believe in Jesus and his sacrifice for us.
You cannot brisge the gap to god by yourself, its impossible, Jesus is the only way to god.
Also confessing your sins help
